To all whom z't may cof/wem.'

Be it known thatI, JAMES G. Pon,-a citizen of the. United States,residin at Dallas, in the county of Dallas and tate of Texas, haveinvented certain new and useful Improvements in Throat Tubes; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as -will enable others skilled in the art to which itappertains to make anduse` the same. i

This invention relates to an improved device to be used while operatingand one object of the invention is to provide a device which may belreadily put in place and removed, one portion thereof being placedbetween the teeth and forming a prop to hold the mouth vopen whileananesthetic is being administered vand the second portion being passedthrough the prop element after the patient has been rendered unconsciousby the anesthetic. By havi'gthe `'prop put in place before the person isanesthetized, the-teethare prevented from contacting and the tube maythus be very easily put in place with its innerend porn tionextendinginto the throat;

Another'object of. the invention is to prof vide Ia device in which thetubular body which is to be inserted through the prop into the throatwill be lprovided with spaced longitudinally extending conduits whichterminate at their outer ends in tube extensions curved towards thesides so that rubber tubes connected with these tube extensions will'not be bent and free passage through the tubes prevented.

Another object of the invention isto provide a device of the characterdescribed in'- which the tubular body may have the conduits in spacedrelation and this tubular.

body-v provided adjacent its inner'end with a side openin terior of theody between the conduits.

vide a device which will be so constructed that it will be firmly iheldin place by the teeth land will have notendencyjto rotate Sltion. ,l

` duce.and which may be'veryeasily cleaned and kept sanitary.

This invention 1s lllustrated in the accompanyingdrawing, wherein:

Figure 1 is a view showing the device parcommunicating with "the in-Another obj ect of thefinven'tion is to protiallyl in planand partiallyinlongitudinal section.

' Figure 2 is a view showing the device in side elevation.

Figure 3 'is a view showing the device in end elevation.

Figure 4i is a longitudinal sectional view through the dev-ice.

Figure 5 is a perspective view of the prop element.

Figure 6 is a sectional view through the prop element.

' Figure 7 is al transverse sectionalvview through thetubular body.

This device'includes a prop element to lhold the mouth open and atubular member band 2 also serves to prevent the device from easilyslipping as it ermits of thedevice being firmly grippe A collar 3 isprovided vatl the outer end of the tubular body forengaging the lips orgums and preventing .the prop from-rmoving into the mouth beyond -adesired distance.

,The tubular member 4 which is to -be passed'through the prop and backthrough the mouth into thefthroat is .provided with 'a 'collar 5 at its-outer end for engaging.

the collar 3 and thus limiting inward move- 'ment of the tubular member4: and preventing it from accidentally slipping through the` rop andmoving too far into the ,throat whi e' an operation is bein performed.This tubular member 4 con orms to the shape of the flattened tubularbody 1 andis vprovided with yconduits 6' which extend longitudinally of.the tubularr` member through th'eside portions thereof as shown in'Figs-1A and 7.f These conduits extend fromthe inner end o f the. tubularmember to the outer end thereof and terminate in tube extensions 7-which extend forwardly i from Ithe outer ends thereof and are curvedtowards the sides. 4"Ih'esetubes 7 have their outer end portionsprovided with enlargefirst beput`in place and will be held between theteeth.. The anesthetic will then be ad! ministered until the patient isunconscious and the tubular member will then be passed through the propand will have its curved yinner end portion extending into the throat.With this prop in place, .the tubular member can be easily insertedwithout it being necessary to pry thetceth apart. A rubber hose leadingfrom a bottle of vaporized ether may be connected with one of the tubes7 and a rubber pipe leading from a vacuunr pump may be connected withthe second tube 7. It wilLthus be seen that mucus and blood may be drawnout through one of these tubes 7 and. the anesthetic administeredAthrough the second. The patient may breathe through the main passageofthe tubular member between the conduits 6. The opening l0 reduces theliability of this tube Ll being closed at its inner end. After theoperation is coii'ipleted, the device can be easilyueinoved, the propbeing left in place,

I claim:v

Yl. A. device of the character described comprising-a flat tubular bodyconstituting until the )atient (vains consciousness.

.a jaw prop for insertion between the teeth to hold the mouth open, and'an open-ended tubular'meniber flattened to conform to theY contour ofthe tubular body in cross section and slidable through said same forinsertion Ainto the mouth and throat after a patient has beenanesthetizedwith the prop in place between the teeth, the tubular memberbeing held against rotation by the flattening of the tubular body andmember,

bular igieaeio4 2. A. surgical devibe comprising a tubular bodyconstituting a jawlprop for insertion between the teeth torhold themouth open,

' engagement with the tubular member to hold thesame against rotationwhenpositioned inthe tubular body.

3. The structure of claim 2 having the tumember provided with 'conduitsformed integral therewith and extending longitudinally through the samein spaced relation to leave a breathing space between the conduits, saidconduits terminating in tubes extending from thev outer end of thetubular member'.

ll. The structure of claim 1 having the tubular member provided withconduits eX- tending longitudinally through the saine aiidterminating intubes extending from the outer .end of the tubular' member and curvedtowards the sides, the conduitsv being in spaced relation and thetubular member having one of its walls provided with an opening adjacentits inner end.

5. A surgical device comprising atubulai' b'o'dy provided with a sideport adjacent its inner end'and opening through the side ot the body,and open-ended Vconduits extending longitudinally lthrough vthe bodywith the side port positioned between the conduits. l

6. A surgical devicecomprising a tubular body provided'with a sideopening adjacent its inner end and opening through the side of thebody,` and conduits extending longif tudinally through the tubular bodyupon opposite sides ofthe side opening and termi-` nating i'ii tubesextending from the outer end of the body.V

.In testimony whereof l have hereunto set my hand.
